Danny & The Juniors, individually Frank Maffei, Danny Rapp, Joe Terranova and Dave White, began singing together in the early 1950's at ages 13 and 14 in Philadelphia where they were fans of the local rhythm and blues radio stations. It was there they heard the first stirrings of a new music soon to become known as Rock 'N Roll. The Juvenaires, as they were called then, quickly decided to become part of the new movement and began to perform the new songs as well as their own original material at school dances, local clubs and restaurants.

At that time, record companies were engaged in a frenzied search for young people who could perform the new music. It wasn't very long before they discovered the youths, re-named them Danny & The Juniors and recorded them singing one of their own original songs called At The Hop.

The song quickly became a monumental hit on five continents reaching #1 on the pop, country and rhythm and blues charts. It stands today as the #23 all-time biggest record according to The Billboa
